精度を低下させるといった欠点があった。(Problems to be Solved by the Invention) Generally, the motor shaft of this type of grindstone shaft drive motor is relatively weak in bending rigidity. As mentioned above, in conventional grinding machines, the motor-side pulley is directly supported by the motor shaft trap. When the rotor rotates eccentrically and the gap between the motor rotor and stator becomes uneven, magnetic vibration is induced, which is transmitted to the main body (bed) of the grinder, causing chatter and reducing grinding accuracy. There were drawbacks such as being forced to do so.

This support mechanism for a motor pulley for driving a grindstone shaft is a grinding machine in which a grindstone shaft is driven by a motor via a pulley and a belt, in which a pulley on the motor side is supported by a fixed part via a bearing, and the pulley and the motor shaft are supported by a fixed part via a bearing. are connected via an intermediate member. In this case, a rolling bearing or a static pressure bearing is used as the bearing, and the intermediate member is preferably connected to the pulley or motor shaft with an elastic material interposed therebetween.

A grindstone shaft driving motor 1 is attached to this mount 8. Further, a hollow bearing holding member 9 extending so as to surround the motor shaft 2 is fixed to one end Yc of the motor mounting base 80, and a gap 13 large enough to accommodate the motor shaft 2 is provided in the hollow portion of the bearing holding member 9. It is inserted through. The shaft end VC of the motor shaft 2 is tightly fitted with a coupling 3 having a flange portion 3at, and is fixed to the shaft end by a nut 11VC.

れる。In the illustrated embodiment, a needle bearing 5 and a deep groove ball bearing 6 are mounted on the outer periphery of the bearing holding member 9, and a motor-side pulley 4 is pivotally supported on the outer periphery of these bearings 5.6. A transmission belt 7 is hung between the motor side pulley 4 and a grindstone shaft side pulley (not shown). The tip of the motor-side pulley 4 is fixed by a flange 3ayc bolt 12 of the coupling 3. In this case, an annular elastic body 10 serving as a flexible intermediate member is embedded in the bolt insertion hole of the seven-ring portion 3a, and the bolt 12
When screwed into the tip of the motor-side pulley 4 through the hole in the elastic body 10, the elastic body 10 is tightened by the bolt head and the pulley tip, and the coupling 3 and the motor-side pulley 4 are connected via the elastic body 10. are flexibly connected.

を支持するようにしてもよい。With this configuration, the driving force of the motor 1 is transmitted from the motor shaft 2 to the coupling 3. It is transmitted to the motor pulley 4 and belt 7 via the bolt 12 and the elastic body 10t. At this time, even if the belt tension is applied to the motor-side pulley 4, the pulley 4 is supported by the bearing holding member 9 of the fixed part via the bearings 5 and 6, so the pulley 4 is )K, and therefore, the motor shaft 2VC is not subjected to bending force due to belt tension. Since the bearing 5.6 and the bearing holding member 9 are constructed separately from the motor shaft 2, they can be constructed to have a sufficient Mlm regardless of the capacity of the motor. Note that the needle bearing 5 mainly receives force in the radial direction, and the ball bearing 6 supports force in the thrust direction. Although a rolling bearing was used as the bearing of the motor-side pulley in the above embodiment, the present invention is not limited to this embodiment, and the motor-side pulley may be supported by a hydrostatic bearing.

る効果がある。(Effects of the Invention) As described above, according to the present invention, the pulley on the motor side is not directly attached to the motor shaft, but is supported on a fixed part via a bearing, so that the belt tension acts directly on the motor shaft. This has the effect that the motor shaft can be rotated with high accuracy without any friction, and the grinding accuracy and motor life can be improved by reducing vibration of the motor.
